Story details

Centrica Energy and Delta Capacity signed a partial tolling agreement for the Karppio battery storage project being developed in Teuva, Finland. The facility is planned for 125 MW and 300 MWh; Delta Capacity is building it and will manage the asset long term.

Centrica will optimise and trade the facility across Nordic wholesale, balancing and ancillary-service markets. Commissioning is planned for the fourth quarter of 2027. The agreement is structured to secure part of project revenue while retaining some merchant-market upside.
